Avoid trailing slash in virtual-root
When setting virtual-root from cgitrc, care is taken to avoid trailing
slashes. But when no virtual-root setting is specified, SCRIPT_FILE
from the web server is used without similar checks. This patch fixes the
inconsistency, which could lead to double-slashes in generated links.
